PACKING-MACHINE.

SPECIFICATION. forining" part of Letters Patent No. 724,230, dated March 31, 1903. Application filed August 12, 1902. Serial No. 119.427. (No model;)

To all whom it may concern:

Be it known that I, GEORGE R. WYMAN, a

, citizen of the United States, residing at East Walpole, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Packing- Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in machines for packing granular materials, the invention relating particularly to improvements in machines adapted to receive empty wrappers closed at the bottoms and having open foldable top portions, to carry such wrappers to a position where they are successively'supplied with a predetermined amount of the granular material, to shake said material to reduce the height of the same in the wrapper, to slightly compress the filled package laterally, to fold the top down, to supply glue or other adhesive material to the portions of the top as such portions are folded or slightly subsequent to such folding, to maintain a pressure on such glued portions after the folding and gluing and at the same time to slightly compress the packages laterally, whereby the approximate level of the material is maintained, and to finally deliver the complete packages in position for convenient handling for further packing.

The object of the invention is to carry out these several steps as a progressive operation.

Another object of the invention is to improve the several independent mechanisms by which the successive steps are carried into effect.

Another object of the invention is to improve the mechanism as regards detector mechanism, whereby the absence of a wrapper is detected and waste of the material is avoided.

Another object of the invention is to adjust the lateral-pressure devices with reference to the lateral dimensions of the filled package.

Another object of the invention is to improve the means for positioning the filled package prior to the closing of the top thereof.

Another object of the invent-ion is to improve the folding mechanisni and the gluing or-cementing devices.

Other objects of the invention will appear from the following description and claims.

The invention consists in the peculiar construction of the several parts of each independent group of mechanism and in the combination of said parts.

The invention also consists in the peculiar combination of such of the independent groups of mechanism as may for this particular purpose be brought into dependent relation to carry out the progressive operation.

The invention also consists in such other novel features of construction of particular parts and in the combination thereof, as shall hereinafter be more fully described, and pointed out in the. claims.

In the drawings, Figure 1 representsafront elevation of the improved packing-machine. Fig. 2 represents a plan view of the same. Fig. 3 represents a rear elevation, on enlarged scale, of the parts particularly relating to the top folding and gluing devices and of some of the parts in association therewith. Fig. 4. represents a plan view, also enlarged, of said folding mechanism and some of the adjacent parts. Fig. 5 represents a vertical cross-sectional viewtaken on line 5, Figs. 2 and 4. Fig. 6 represents a vertical cross-sectional view taken on line 6, Figs. 2 and 4. Fig. 7 represents a similar .view taken on line 7,Figs. 2 and 4, and relating particularly to the positioning of the filled package and the gluing mechanism with its detector device. Fig. 8 represents details of the gluing mechanism,

showing the glue-roll in the lowered position,

but sustained out of contact with the parts of the folder devices, as when restrained by the non 'action of the glue-roll detecting device. Fig. 9 represents a vertical cross-sectional view of the machine, taken on line 9, Fig. 2, and illustrating one of the top and side pressure devices and its associated mechanism. Fig. 10 represents an enlarged front elevation of one of the carriers, showing details of the package-lifting devices' Fig. 11 represents an end elevationof the same, showing'the holding-dogs for holding the carrier inposition for the folding and gluing of the upper portion of the wrapper. Fig. 12 represents a plan view of the gluing mechanism. Fig. 13 represents a plan View showing details of the second folder-plate and its controlling means in the first or inactive position. Fig. 14 represents a similar view showing this plate in the position occupied thereby after its folding operation has been accomplished. Fig. 15 represents these parts in elevation and in association with their actuating-cam, the cam-shaft being shown in section, as on line 15, Fig. 4. Figs. 16 to 20, inclusive, represent diagrams of the filled package in the folding position with the various positions occupied by the folder-blades in accomplishing the folding and returning to their initial positions, also showing some of the features of construction. Fig. 16 represents the relations of the blades when the filled package is in the folding position. Fig. 17 represents the first fold as having been made, the first folder-blade remaining in position as completing said fold and the second folder-blade as finishing its folding movement. Fig. 18 represents the first folder-plate as still resting in its fold and the crease-plate of the third folder brought to position for creasing the last fold, the third folder-plate being swung backward beyond the triangular last fold ready for the forward movement to engage the last-folded portion when the end of such portion is raised above the edge of the last folder. Between the positions shown in Figs. 17 and 18 the glue is applied in a strip along the edge of the fold made by the sec end plate. Fig. 19 represents the retraction of the first folder-plate and the swinging forward of the last folder-plate, the first action of said plate being to force the triangular last fold overthe edge of the creaser-plate and then subsequently to press this triangular portion down onto the top of the package as the creaser-plate moves away. Fig. 20 represents these parts in their relative positions as the folding is completed and slightly after the onward movement of package has commenced, showing the ironing action of the last folder-plate on the folded and glued top of the package. Fig. 21 represents a vertical cross-sectional view of the supply-hopper and its detector mechanism, whereby the absence of a wrapper in the carrier beneath said hopper is detected and the supply is diverted. Fig. 22 represents a vertical sectional view of the same, taken at right angles to Fig. 21.

Similar nu merals of reference designate corresponding parts throughout.

In carrying this invention into practice I construct a strong and substantial frame in the nature of a supporting-base, preferably having the front and back members and 31 and the cross-bars 32 and 33 and supported on the standards 34 34; but it is evident that any suitable base may be utilized and that it may be braced and otherwise strengthened in any usual manner.

Mounted on the members 30 and 31 at the respective ends of the frame are bearings 35 35 and 36 36, and in these bearings arojournaled the shafts 37 and 38, each of which has a sprocket-wheel 39 and-40 and a ratchet 41 and 42, and on each of the shafts is pivotally mounted an arm 43 and 44, having a pawl 45 or 46, adapted to engage the teeth of its associated ratchet when the arm isswung and to thus cause the intermittent rotation of the shafts with their sprocket-wheels.

About midway in the length of the frame are mounted bearings 4747, in which the main shaft 48 is journaled, and on this shaft is mounted the cam 49 and the gears 50 and 51. Working over the shaft is the frame 52, having the arm 53, provided at one end with the roller-bearing 54, working against the face of the cam 49, the other end of the arm 53 being pivoted to the lever 55, which is in turn pivoted on a stud projecting inwardly from the frame member 30, the lower end of this arm being connected with the pawl-arms 43 and 44 by the rods 56 and 57, pivoted to said lever and to the respective pawl-arms. Thus at each rotation of the shaft 48 the lever 55, being retracted by the spring 55, is vibrated, and through the rods 56 and 57 and their connections the ratchet 41 and 42, with the shafts 37 and 38 and their sprockets 39 and 40, are intermittently rotated.

Extending between the upper portions of the sprockets 39 and 40 are rails 58, suitably supported on brackets, as is shown in Figs. 5 and 7 of the drawings, and extending beneath the operative portions of the machine at a distance therefrom is the guard 59, having the curved ends 60 and 61.

Working over the sprocket-wheels 39 and 40 is an endless belt formed of a series of carriers, Figs. 10 and 11, connected and suitably distanced by the links 62 62, pivotally connected at the ends to the base portions of said carriers.

The carriers (shown in Figs. 10 and 11) are open at the front and back, having the bases 63, provided with the end pieces 64 64, extending upward asuitable distance, the open space between such end pieces being adapted to receive a package of a predetermined size. The bases of said carriers have openings, as 65, Fig. 10, formed at their sides, and in the bases are mounted the vertically-movable bottoms 66, having the pins 67 and being connected with their respective bases by the retractingsprings 68 68. On the pivots connecting the bases 63 with the links 62 are mounted wheels or rolls 69 69, which ride on the rails 58 58.

At the feeding and ejecting end of the machine is a receiver 70, by which the filled carriers travel. Slightly above the open end of this receiver is positioned a support 71, adapted to receive the empty wrapper a, and working over this support is the feedingpusher 72, fixed on one arm of the bell-crank lever 73, to which arm the ejector 74 isalso fixed. This bell-crank lever 73 is pivotally supported by means of a pivot mounted in the arm 75 and is intermittently operated by the connecting-rod 76 and the lever 77, suitably pivoted, and actuated by the rod 78, which is reciprocated by the action of the cam 79 on the shaft 48 at each forward movement of the carriers, so that an empty wrapper or container placed on-the support 71 is pushed into the carrier opposite this support by the pusher 72 at the same time that a filled and sealed package is ejected by the ejector 74 from a .carrier opposite the receiver 70.

Adjacent to the bearings 47 47 are mounted the bearings 80, in which is journaled the shaft 81, furnished with the small gear 82, meshing with the large gear 50, and provided at its other end portion with the belt-pulley 83. At a distance from this shaft 81 is journaled the shaft 84, furnished with the beltpulley 85, considerably smaller in diameter than the pulley 83, the shaft 85 being driven at a high speed by the belt 86, working over the pulleys 83 and 85, and to the forward end of the shaft 81 is secured the crank 87, carrying the pivoted arm 88, the use of which will hereinafter be described.

On the members 30 and 31 are mounted the braces 89 and 90, portions of which extend upward to support parts of themachinery. The brace 89 has an extension 91, on which the arm 75 of the feeder and ejector mechanism is pivoted, and these braces are provided with bearings in which the rock-shaft 92 is journaled, this shaft having a laterally-extending arm 93, which is pivotally connected with the upper end of the arm 88 ofthe crank 87, so that when the shaft 84 is driven the shaft 92 is rapidly rocked to rapidly vibrate the shaker-arms 94 94, fixed to said shaft 92, the extensions 95 95 of which are positioned to act on the rod 95, on which the pins 65 of the carriers travel from the filling position nearly to the gluing position.

Secured to the frame members 30 and 31, between the bracket 89 and the bearings 35, is the frame 96, carrying at its'upper portion the deliveryhopper. (Shown enlarged in Figs. 21 and 22.) This hopper comprises a casing 97, having the inlet 98, adapted to receive periodical supplies of a predetermined quantity, and the outlets 99 and 100, the outlet 99 being positioned or having an extension, preferably as shown at 101, to deliver material from the hopper to an empty wrapper brought beneath the same, and the outlet,

100 being designed to deliver the material in a different direction from that of the outlet 99. Near the lower portion of the casing 97 is journaled the shaft 102, carrying the upwardly-extending flap-valve 103, closely fitting the interior of the casing to work therein. The outer ends of the shaft 102 are furnished with the balance-weights 104 and 105, the weight 105 having the arm 106, on which the weight 107 is adjustable. From the upper portion of the casing 97 extends the bracket-arm 108, and on the pivot of this arm is pivoted the detector 109, having the detector-frame 110 and connected with the balance-weight 105 by the retractingspring 111. The frame 110 extends along one side of the path of the carriers 64, and spring 111 tends to draw the same across said path until brought to a position where the weight 107 is allowed to swing the shaft 102 to throw the valve 103 to the position shown in dotted lines in Fig. 21 to direct the material through the outlet 100.

' The detector-frame 110 is normally held in the position shown in full lines in Fig. 21 by the upper portion of the wrapper a, and it will be noticed by reference to Fig. 1 of the drawings this frame .is sufficiently long to span the distance. between two of the carriers, so that it will not swing between the wrappers in adjacent carriers. By the use of this hopper and its detector the material is diverted from its movementtoward the carrier The standard 112 is secured to the frame member 30 in proximity to the bearing 47 thereof and extends upward, being provided with a bearing for the rock-shaft 92 and at its upper end with a bearing for the handshaft of the glue-roll, to be hereinafter described. Between this standard 112 and the frame 96 extend the guides 113 113 at the sides of the path in which the carriers travel.

Secured to the frame members 30 and 31 are the frames 114, 115, and 116, which are suitably spaced, and in perforations of these frames are journaled the shafts 117 and 118, while in the frames 114 and 115 are fixed the shafts 119 and 120, the frames 115 and 116 being of similar construction.

In the upper arm portions of the frame 114 are the guides 121 and 122, in which are movably mounted the slides 123 and 124, the guides 121 having the perforated ear 125. On the slide 123 is fixed the vertical sidepressure plate 126, furnished at its upper end with the spring projection 127, and the slide 124 is provided with the vertical side-pressure plate 128, having the bracket-shelf 129, a plan View of which is shown in Fig. 4. This plate 128 is perforated to receive the detector-rod 130, carrying thedisk 131, the rear end of this rod being pivoted to the downwardly-extending arm 132 of the bell-crank 133, pivoted to the bracket-shelf 129.' From the rear of the plate 128 also project the perforated projection 134 and thearm 135. On this arm is pivoted the tripper-plate 136, supporting on one end the spring-depressed pin 137, which works through the perforation in the projection 134 and through ,a corresponding perforation in the bracket-shelf 129. From the frame 114 also projects the studshaft 138, and on this shaft is mounted to when said carrier is brought to the gluing or sealing position, the outer endportions ,of

this lever being furnished with the projecting sleeve-bearing 141 and the adjustable balance-weight 142.

On the shaft 119 and 120 are respectively mounted the dogs 144 and 145, having inwardly-turned ends 146 and 147, adapted to engage in the recesses 65 of the carrier-bases when the carriers are brought to the gluing position. The bosses of these dogs are supplied with gear-teeth 148 and 149, which intermesh, and the boss of the dog 145 has the projection 150 working on a pivot which extends from the lever 151, this lever having a forked end which engages over the cam-shaft and a projecting bearing-stud 152.

Fixed on the shafts 117 and 118 are the arms 153 and 154, having slotted upper ends in which the slide-blocks 155 and 156, Fig. 5, work, these blocks being engaged with the pins projecting from the respective slides 123 and 124 to reciprocate the slides, and thus bring pressure on the sides of the package located therebetween by means of the plates 1 126 and 128 when said shafts are rotated.

The rotation of the shafts 117 and 118 is effected by means of the lever 157, fixed on said shaft and having its outer end provided with a bearing-stud 158 and at its inner end the segmental gear 159. On the shaft 117 is journaled the arm 160, having the segmental gear 161, which meshes with the gear 159, and the member 162, on the upper end-of which is pivoted the socket-piece 163, having a screwthreaded socket and the rack 164. Fixed on the shaft 117 is the arm 165, having pivoted to its upper end the fitting 166, having a pivot on which the dial-pinion 167 works to engage the rack 164. lhis fitting is also furnished with a transverse perforation in which the shaft 168 works, the screw-threaded end of the shaft engaging in the threaded socket of the socket-piece 163 and being adapted to be rotated by the crank-arm 169 and its handle to adjust the separation of the upper ends of the members 162 and 165 and to thus determine the point of engagement between the segmental-gear portions 159 and 161, and thus the swing of the arm 160, to thereby regulate the movement of the slide 123.

Mounted on the frame member 31 are the bearings 171 and 172, and in these bearings is journaled the cam-shaft 173, provided with the bevel-gear 174, which meshes with and is driven by the complemental gear 51 on the main shaft 48. Fixed on the cam-shaft are a the cams 175, 176, 177, 178, 179, 180, 181, and

ate the arm 150 to close the dogs 144 and 145 and engage the ends 146 and 147in the recesses of the carrier-base to hold the carrier from movement.

Immediately after the locking of the carrier by the dogs 144 and 145 the cam 181 reaches a position in relation to the stud 158 of the lever 157 to elevate this end of the lever, and thus rotate the shafts 118 and 117 through the connections therewith and to cause the inward swinging of thearms 153 and 154 to carry the slides 123 and 124,with their resser-plates 126 and 128, toward the package.

At one side of the cam 176 is secured to the member 31 the standard 183, forming,with the standard 184, the support for the gluing mechanism. The standard 183 has the guide 185, in which the rack-slide 186 is movable, a bearing 187 (see Fig. 4) workingin the path of the cam 176 to reciprocate this slide at times. The upper portions of said standard are connected by the cross-piece 188, having the bearings 189 189, and above this cross-piece is the frame 190, carrying the shaft 191. On one end portion of this shaft 191 is pivoted the arm 192, having the arm 193 and the plate 194, and on the frame adjacent to the path of the arm 192 is mounted the adjustable stop 195 for limiting the forward movement of said arm, the lever 196 being pivoted on a stud which projects from the standard 184 and being engaged at its upper end with the pin 193 of the arm, while its lower end is provided with the roll 197, bearing on the periphery of the cam 179, whereby at times the arm 192 is swung to bring the plate 194 against the rear upper portion of the filled package.

Secured to the frame 114 and sustained in part by a portion of the bracket 183 is the cam-plate 198 of the second folder-plate mechanism. (Shown in Figs. 13 and 14.) At the forward edge of this plate at one side is formed the open bearing or stop 199, and from this forward edge opens the cam-slot 200, the primary curve of which from the opening being practically concentric with the curve of the bearing 199 and the slot then curving eccentrically to the axis of said bearing first slightly toward said bearing and then away from the same, as shown.

From the standard l83vextends the bracket 201, having vertically-perforated bearings 202 202. In these hearings is journaled the shaft 203, having at its upper end portion the gear 204 and at its lower end the gear 205, which latter gear meshes with the teeth of the sliderack 186. On the shaft 203 is pivoted the bearing-sleeve 206, which is connected to the bearing-sleeve 207 by the arms 208 208, and in the sleeve 207 is journaled the shaft 209, having the gear 210, meshing with the gear 204 and carrying the second folder-plate 211, having the upwardly-curved edges 212 and 213, between which at the free end of the plate IIC is the creasing-lip 214, the edge 213 being short, as the portion of the material toward the pivoted part of the blade is cut away to provide clearance. Immediately below said plate are the stop-arms 215 and 216, which are connected by the spring 217 with the shaft 209. The lower end of the shaft 209 is finished with the hub 218, adapted at times to be rotatably located in the bearing 199, and from this hub extends laterally the arm 219, having the projection 220.

When in the position shown in Figs. 4and 18, the plate 211 is ready to start its folding movement, the hub 218 being in'the bearing 199. The backward movement of the rack 186 from this point through the action of the cam 176 causes the rotation of the gear 205 with its shaft 203 and the gear 204 in the direction of the arrow in Fig. 4, thus rotating the gear 210 and its shaft 207, with the blade 211, until the blade is brought to the position slightly beyond that shown in Fig. 17, the projection 220 in the meantime swinging through the concentric portion of the cam-slot 200 and out of the open end thereof. The rack 186 having at this time reached the limit of its backward movement is now driven forward and causes the reverse rotation of the gear 205 and its related rotative mechanism, thus swinging the blade forward and bringing the projection 220 through the concentric portion of the slot 200 to the forward curve of said slot. If the blade 211 be left in this position, Fig. 13, it will interrupt the next approaching unsealed package. The forward movement of the rack 186 is therefore contin ued, as is also the rotation of the gears 205, 204, and 210. The projection 220, working through the forward curve of the slot 200 and its arm 219, first pushes the hub 218 from the open bearing 199 and then entering the long backward curve of the slot 200 carries the shaft 207 and its related mechanism backward until said projection has traversed nearly the length of this portion of the slot until the forward movement of the rack has ceased. Byvthis mechanical movement the blade 211 is drawn from between the carriers to a position where it cannot interfere with the next approaching package. At the initial rearward movement of the rack 186 the motion just described is reversed. When the projection 220 enters the forward bend of the cam-slot, it swings the hub 218 around the projecting portion of the open bearing 199 and then draws the same into that hearing ready for rotation. At the limits of rotation of the shaft 209 the stops 215 and 216 alternately bear against the shaft 203, the stop 215 yielding slightly against the action of its spring 217.

Extending from the frame 1.14 is the stud 221, on which is journaled-the sleeve 222, having the rearwardly-extending lever 223, the bearing-stud 2240f which isengagedin the campath of the cam 180, as shown in Fig. 5, and the upwardly-projecting member 225, and to this member is adjustably secured the first folder-plate lever 226, having the stop member 227, in which the stop 228 is screwed, the stop 228 being adapted to be intercepted by the bufier 229, secured to the frame 114. At the upper portion of the lever 226 is pivoted the arm 230, provided with the first folderplate'231 of a size and shape proportioned to the size and shape of the package under operation, as shown in Figs. 16 to 20, this arm 230 having the member 232 furnished with the roller-bearing 233 and connected by the tension-spring .234 with the stop member 227, the strain exerted by said spring tending continually to swing the free end of the folderplate 231 upward.

0n the frame 30 is secured the bearing 235, in which is pivoted the shaft 236, having the arms 237 and 238. The arm 237 bears against the cam 239 on the main shaft 48 and is depressed at times by said cam. On the arm 238 is supported the standard 240, having at 114, the link being pivoted at its ends to said parts to permit the elevation of the standard 240 at times. Under the action of the downward motion of the movable end of the lever 223 the arm 226 swings inward, the generally horizontal position of the plate 231 being maintained by the. bearing 233 of the controller-arm 232, working over. the cam-path 241, until the arm 238 is raised by the action of the. cam 239 on the arm 237, when the free end of the plate 231 will be depressed, this occurring as the limit of inward movement of the plate is reached, the arm 238 being again depressed to permit the retraction of the plate 231 in a horizontal path.

On the lower portion of the standard 184'is the guide 243, in which the rack-slide 244 is movable, the stud 245 of the rack-slide enbearings of. which the shaft 247, having the gear 247, is journaled, and at the upper p01 tion of this shaft is fixed the third or last folder-plate 248, having the upwardly-curled straight front edge 249 and the curling and curved rear edge 250. Also mounted on this shaft 247 is the crease-plate 251, having the straight beveled edge 252 and the end 253 at one side of said shaft and the stop-lips 254 and 255 at the other side of the shaft. This'latter plate is journaled on the shaft and is normallyheld in position by the coiled spring 256, secured to said plate and to the shaft. From the standard 184 extends the stop 257, which at times is adapted to intercept the stop 255 of this plate 251.

Pivoted on the shaft 258, which-projects from a portion of the standard 184, is the lever 259, provided with the roller-bearing 260, which rides on the periphery of the cam 180. At its forward end this lever has the stop 261 and the tripper-finger 262. (Shown in Fig. 4.)

swinging of the stop-pin 264 being limited by the stop 261 on said lever, the office of the stop-pin 264 being to strike the stop 2540f the crease-blade 251 and to force said stop 254 along to retract the edge 252 until said pin 264 is intercepted by thestop 261.

Journaled in the upper rear portion of the frames 115 and 116 is the shaft 265, carrying a series of presserarms 266 266, mounted to swing thereon and disposed with relation to the positions of the carriers when at rest. These presser-arms have each a yoke 267, through which extends an arm 268, fixed to said shaft 265 and having a depending stop 269, the rear end of each arm 268 being connected with the lower end of its related presser-arm by a retraction-spring 270. Each presser-arm is also furnished with a stop 271, corresponding to the stop 269 of the related arm 268, and at its forward end is curved over the path of the carriers and is provided with a more or less elastic cushion 272. On the shaft is fixed the arm 273, which extends downward and has a stud 274, which engages with a cam-path of the cam 182, this cam-path being shaped to at times-cause the elevation and depression of the free end of the arm 273, thus raising and lowering the outer ends of the arms 268 and drawing the rear ends of the Presser-arms 266 upward by means of the spring connections to press the cushions down on the recently-sealed ends of the package 0 c, the lifting of the presser ends of the arms 266 being efiected by the weight and leverage of those portions extending rearwardly from the shaft 265.

Fixed on those portions of each of the shafts 117 and 118, which extend beyond the frame 115, is a series of upwardly-extending arms, as 275 and 276, Fig. 9, the respective series at each side of the carrier-path being con-.

nected by a longitudinal member 277 or 278, and on these members are mounted the shanks 279 or 280 of the respective front Presser-plates 281 and the back presser-plates 282, positioned to be pressed against the corresponding portions of the packages when the carriers are at rest. At the lower portions of the frame 115 and 116 are fixed the shafts 283' and 284, carrying the freely-swinging arms 285 and 286, the upper ends of which are connected with the similar portions of the arms 275 and 276 by the rigid links 287 and 288, pivoted to their respective arms.

The ripper portions of the frames 115 and 116 are furnished with the inwardly-extending portions 289 and 290, on which are mounted the guides 292 292, between which the carriers move and which prevent the falling of the packages from the carrier.

The upper rails 58 58 extend through that portion of the machine where the folding and sealing of the packages is effected, being supported by brackets extending from the rails 58 58 or in any other suitable manner. The office of these upper rails is to prevent the rising of the carriers while the package is'under operation or during the lifting of the package by the arm 139 preliminary to the sealing operation.

Now returning to that part of the machine opposite to the location of the package at the time of sealing and folding it will be seen that in the ears 189 189 of the cross'frame 188, Fig. 3, is journaled the shaft 293, having the fixed arm 294, the free end of which rests on the end of the pivoted tripper-plate136, and the fixed cam-arm 295, the projection 296 of which rides on the periphery of the cam 178 and is elevated at times by the shoulder 178' and almost immediately permitted to drop as the straight face of the shoulder 178 is brought in line with the clearance of the projection 296 of said arm, the office of these arms 294 and 295 being to elevate the pin 137 to lift the rearwardly-extending flap of the package-wrapper when the third folder-plate has swung back and is about to move forward to permit the front edge of the folder-plate to engage under said flap, as will hereinafter be described, the pin 135 being then retracted by its spring to avoid the interception of the third folder-plate as it moves forward.

The shaft 191, as stated above, is journaled in bearings of the frame 190. At one end of this shaft is fixed the gear 297, overa portion of which extends the guide-frame 298, and in the guide-frame is movably mounted the rack 299, in engagement with the teeth of the gear 297, the arm 300 forming an extension of such rack and being provided with a stud 301, working in the path of the cam 175.

On the shaft 191 is journaled the sleeve 302, Fig. 7, having the arm 303, pivotally connected with the crank-lever 133 by the rod 304 and the tripper 305, the spring-support extending rearwardly from said sleeve.

Fixed on the shaft 191 are the arms, as 307, having the projection 308, to which the latch 309 is pivoted, and on the arms 307 is pivoted the glue-delivery roll-frame 310, furnished with the glue-delivery roll 311, with its gear 312, Fig. 12, at its lower end and at its upper end with the roller-bearing 313 and the catch 314, with which the end of the latch 305 is adapted to be engaged, the upper end of the glue-roll frame being connected by the spring 315 with the pin 306, which spring tends to draw this end of the glue-roll frame inward to bear against the face of the cam 316, adjust-ably secured to the frame and suitably shaped for the direction of the glue-roll 311 when the bearing 313 rides thereon.

One portion, 190, of the frame 190 (shown in Fig. 7) extends over that portion of the machine at which the package is sealed, being supported at its forward end by the bracket 317, which is secured to the frame 114. On the front portion of the frame member 190 is 1 toms of the wrappers being closed.

secured the glue-reservoir 318, preferably removable therefrom, this reservoir being furnished with the glue-supply roll 319, rotatable in bearings and having a gear 320. The reservoir is also provided with side plates 321, in which the shaft 322 works, and on the ends of the shaft are fixed the arms 323, between the ends of which is journaled the shaft on which the glue-distributing roll 324 is journaled. Also fixed to the shaft 322 is the spring stop-arm 325, extending laterally therefrom to rest under the adjusting-screw 326 of the cross-bar 326, mounted on the side plates 321 of the reservoir, by the adjustment of which the pressure of the roll 324: on the supply-roll 319 is effected. The member 190 of the frame 190 is also provided with the bearing-brackets, as 327, Fig. '7, and in these brackets is journaled the glue-drive shaft 328, having the beltpulley 329 and the gears 330 and 331. On this shaft is journaled the arm 332, on a stud at the outer end of which is rotatable the idle pinion 333, intermeshing with the gear 331. A handle 334 is fixed to said arm, by means of which the arm may be swung about the shaft 328, provision being made to adjustably secure this handle to some fixed part of the machine, this adjustment being desirable-in order to so position the pinion 333 that it may be engaged by the gear of the glue-delivery roll 311 as the latter swings into contact more or less with the supply-roll 319 and to permit of such approach, the glue-delivery roll being thus rotated while taking a supply of glue from the roll 219, the engagement of the gear 330 with the gear 320 of the supply-roll at the same time driving the supply-roll in the same direction, but preferably at a different speed. The glue-r011 shaft 328 is driven by the belt 335, Fig. 1, working over said pulley, under the guide-pulley 37, rotatably mounted in the bracket 336 of the member 30, and around the pulley 337, secured to the shaft 81, which shaft is driven by the engagement of its gear 82 with the gear 50.

Mechanism of any well-known construction being associated with the hopper 97 to deliverthereto periodically granular orother comparatively loose material in predetermined quantities, the operation of the machine is as follows: Wrappers aaare placed one at a time on the surface of the support7ateach outward movement of the feeder 72 and between said support and the path of the carriers and are by this feeder pushed into the carrier which is at rest beside said support at that time. These wrappers are shaped in cross-section to be received by the carriers, as is in Fig. 16 of the drawings, and have longitudinal dimensions considerably greater than the height of the ends 64 of the carriers, the bot- The intermittent driving forward of the carriers by means of the connections between the driveshaft 48 and the sprockets 39 and 40 brings the carriers in succession beneath the spout or fitting 101 of the hopper 97, and the predetermined amount: of material simultaneinto the open end of the wrapper a to fill it to a level slightly above the upper ends of the carrier when such wrapper is present in the carrier therebeneath at the time such material passes through the hopper, this direction of the material being effected by that portion of the wrapper extending above the carrier bearing against the detector-arm 110 and holding it in the position shown in full lines in Fig. 21 of the drawings. When no wrapper is present in the carrier beneaththe hopper 97, the detector-arm 110 is permitted to swing to the position shown in dotted lines in Fig. 21 of the drawings, and the flap-valve 103 is brought to the position (also shown in dotted lines in said figure) to direct the material through the outlet 100 into a suitable receiver. As the carriers are successively brought beneath the supply-hopper they enter between the guides-113 113, which prevent undue lateral movement of the filled wrapper h. At the same'time the pins 67 successively ride onto the upper surface of the shaker plate or member 95, which being constantly and rapidly vibrated by the action of the crank 87 and the connections between the same and this member causes the rapid reciprocation of the pins and the raising of the bottoms 66 of the carriers, the springs 68 68 tending to draw these bottoms 66 downward. It will therefore be seen that the material entering the wrapper is shaken and compacted as it enters the wrapper and in comparatively small quantities, continually increasing, thus eifecting a close packing of the contents. This shaking is carried on continuously after the delivery of the maloo 7 terial until the tilled package nears the folding and sealing position; but it is evident that this invention is notintended to be limited to the particular point at which the shaking commences or ceases. At ti mes it becomes important to exert lateral pressure on the exposed sides of the filled wrapper to crowd'the material therein upward, and one of the positions in the progressive operation where this pressure is particularly desirable is at the time ofsealing. In viewof the varyingcubical dimensions of various material of the same Weight and'the similar variation in difierent grades or lots of the same material, such as coffee, it is essential that these pressure-exertingdevicesshould bereadilyadjustable. After the filling of the wrapper and the shaking of the contents the carrier reaches the position tween the plates 126 and 128, Fig.5 of thedrawings. At or about the same time the rolls 69 69 of the carrier-base ride under the upper rails 58' 53. Thus the lifting of the carrier is prevented, the recesses 65 65 are brought opposite the dogs 146 and 147, and the pin 67 of the carrier-base is positioned above the lifter end 140 of the lever 139. The arms 144 and 145 are now operated by their connections with the cam 178 to engage their dogs 146 and 147 in the recesses 65 of the carriage-base to prevent the longitudinal movement. About the same time the cam 177 has rotated to a position where the weighted end of the lever 139 is permitted to move downward, thus elevating the end 140 of the lever, and with it the pin 67 of the carrier, with the platform 66'and the filled wrapper Z) thereon, to bring the level of the material therein to a suitable height for receiving the folded portions of the upper end of the wrapper. As the filled wrapper is raised to the sealing position the side-pressure plates are moved inward under the action of the arms 153 and 154 and their driving mechanism until the desired pressure is brought on the front and back of the filled wrapper, the pressure being determined by the adjustment of the arms 162 and 165 by means of the handle 169 and its shaft, whereby the point of engagement between the toothed ends 159 and 161 of the arms 157 and 160 is adjusted to determine the rotation of the shafts 117 and 118, and thus the swing of the arms 153 and 154. When the plate 128 moves inward to press against the rear side of the filled wrapper I), the forward movement of the detector 131 is limited by the wrapper, while the plate 128 moves into contact with said wrapper. This effects the swinging of the arms 132 and 133, fixed to their pivot, forcing the rod 304 and the free end of the arm 303 upward to rotate the sleeve 302 and press the tripper 305 against the latch 309 and move said latch from its engagement with the catch 314 to permit the spring to act to draw the roll 312 against the guiding-face of the cam 315. By this time the cam 178 has been rotated to the position shown in Fig. 5 of the drawings, where the stud end of the lever 23 is depressed, thereby throwing forward the member 225 and the arm 226 to force the edge of the first folderplate carried by the lever 230 inward against the front portion of the wrapper and to fold the same inward. About this time the reinforce-plate 164 is moved into position against the back of the wrapper, as shown in dotted lines in Fig. 6 of the drawings, to reinforce this portion of the wrapper against the action of the first folder-plate. Slightly after the starting inward of the first folder-plate the arm 238 is raised by the depression of the arms 237 under the action of the cam 239, thus elevating the standard 240, with its camfaee 241, over which the bearing 233 of the folder-plate arm works, this causing the elevation of the bearing 233 and the consequent gradual directing downward of the edge of the folder-blade as it approaches the end of its throw and effecting the crowding downward and turning inward of the front and portions of the sides of the wrapperabove the contents thereof. The cams 178 and 239 are so proportioned to now permit a dwell of the first folder-blade until a further point in the operation has been accomplished, and at this time the reinforce-plate 194 is moved upward. During this dwell the second folder-plate 211 is swung, as above described, from the position shown in Fig. 16 of the drawings over the package, the edge 212 smoothing down this side portion thereof until the drawing action of that side portion and the bending backward of the rear portion onto the support 129 effects the drawing down of the last side, as is shown in-Fig. 17 of the drawings,

and the lip 214 of this folder-blade working beneath the edge portion g of this last fold and creasing the angular fold of the last turned-down portion as said lip leaves the triangular flap. Under the movement of the rack 244 the gear 247 and its shaft 247 are rotated at this time to swing the plates 248 and 251 backward over the end of the package, the edge 250 of the plate 248 smoothing the surface of the folds and pressing the triangular flap down onto the support 129. The plate 251 swings in this direction until its creasing edge 252 is brought nearly to the surface plane of the real-surface of the package, when the further movement of this plate is prevented by the fixed stop 257intercepting the stop-arm 255 of said plate, and this plate then rests in the position shown in Fig. 18 of the drawings, while the plate 248 moves to the end of its throw and partially returns. Immediately prior to the return of the plate 248 the projection 178 of the cam 178 reaches a position in relation to the end 296 of the arm 295 to raise this end of the arm and to quickly drop the same. The arm 294 is thus caused to swing on its shaft and to depress the end of the tripper-plate 136 to throw the pin 137 upward against the retraction of its spring. By this means the triangular flap is raised from the support 129, so that the edge 249 of the plate 248 engages under said flap, while the spring of the pin 137 retracts said pin from the path of this blade. The return movement of the blade 248 folds the flap over the edge 252 of the blade 251 snfliciently to form a bend at the juncture of the flap with the main portion of the wrapper. At or about the time the estension 255 of the plate 248 is intercepted by the stop 257 the downward movement of the glue-roll to apply glue in a strip along the portion of the triangular flap indicated in dotted lines in Fig. 18 of the drawings commences, the direction of the glue-roll 311 being controlled by the bearing-roll 313, Working over the irregular face of the cam 316 under the tension of the spring 315, while the glue-frame is carried down and returned by the swinging of the arms 307. In order that the glued strip of the triangular flap may be folded down onto the first inward fold of the wrapper, it is now necessary to withdraw the first folder-plate 231 and the crease-plate 251 from interference with such contact, this re- 'on the upper surface of the contents.

fnoval also being essential to prevent the application of glue from the triangular flap to the crease-plate. The initial return movement of the crease-plate is illustrated in Figs. 18 to 20, inclusive, of the drawings and is offected by the actuation of the pin 264 when the tripper 262 of the lever 259 strikes the pivoted arm 263, to which the pivot of said pin is secured, and the movement of this pin being limited by the stop 261 on said lever. The pin 264 acts on the extension 254 of the crease-plate when said plate rests in the position shown in Fig. 18 of the drawings and causes the swinging of the plate to the partially-retracted position (shown in Fig. 19) against the action of the spring 256. Approximately at the time this partial retraction of the crease-plate is taking place the return movement of the first folder-plate commences, and attention is here directed to the relative positions occupied by the plates, as illustrated in Figs. 17 and 18 of the drawings. In such figures it will be noticed that the plate 251 laps over the first folder-plate 231 and that the inturned side flaps of the wrapperare pressed down onto the upper surface of the plate 231 by the plate 251, the plate 231 pressing the first inturned portion of the wrapper A downward movement of the first folder-plate in its withdrawal would bring undue end pressure on the contents of the package, while an upward movement of such plate is prevented by the overlapping crease-plate. It will therefore be seen that by the use of the cam 241, mounted on the vertically-movable standard 240, the action of the controller-bearing 233 may be such that the plate 231 can be withdrawn from the position shown in Fig. 18 of the drawings without deflection from the planes of its upper surfaces. As the creaseplate 251 and the first folder-plate 231 are retracted the third folder-plate 248 continues its return movement under the action of its shaft 263 and having engaged the lower surface of the triangular flap, as above described, turns the glued portion of this flap down onto the exposed surfaces of the previously-formed flaps and smooths the same down. On reaching the position shown in Fig. 20 the edge of this plate 248 engages the edge of the crease plate and swings said plate to the position shown in Fig. 16. During this latter move-- ment of the plates 248 and 251 the first folderplate 211 has moved approximately to the position shown in Fig. 20 of the drawings, the dogs 146 and 147 have been released from engagement with the carrier, and the end 140 of 0 again under the smoothingaction of the plate 248, while the next carrier is advanced to the sealing position. Should an empty carrier be brought into the sealing position, the detector 131 meets with no resistance in its forward movement, and no action of the tripper 305 takes place to trip the latch 309. Hence the drawing inward of the spring 315 of the bearing 312 is prevented by the latch 309 remaining in engagement with the catch 313. The arms 307 will then swing the glue=roll frame and move the glue-roll in an are above the folder-plates, wherebythe application of glue to said plates is prevented. From the sealing position the sealed packages 0 c are carried forward by theintermittent driving devices to the positions where side pressure is brought against them by the pressure-plates 281 and 282, while the springs 270 arepermitted to act to depress the ends 272 of the levers 266 into contact with the sealed ends of the packages to provide intermittent pressure thereon while the glue is setting. Any desired number of these side and end pressure devices may of course be used. The packages are finally carried around the sprocket-wheel 40, being held in the carriers by frictional. contact and by the guard 59, this guard efiecting a further smoothing of the sealed ends of the packages,and the packages being returned to the starting end of the machine are automatically ejected from the carriers by the ejector 74.

The term packing-machine is herein used to designate a machine by the operation of which material maybe packed in wrappers, cartons, or other containers which have been previously constructed in so far as they are prepared to receive the material as one of the steps in the operation of the machine.

It is evident that wrappers of different sizes within certain limits may be used in this machine, this being particularly noticethe side-pressure plates whereby this pressure is proportioned to the cross-sectional dimensions of the package.
